Abstract: A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

An offset signal component (402) is then identified (312) from the receive electrical signal (400), the offset signal component (402) arising from the background ambient component of the received electromagnetic radiation (118). The gain factor from the offset signal component (402) is then estimated using a characterisation of the offset signal component (402), and the reflectivity is calculated using the receive electrical signal (400) and the estimated gain factor.

Title: Display apparatus and method for preventing image burn-in thereof
Inventor: LIN CHENG-LUNG
IPC: G09G3/3208
Filed: 2022-06-02
Abstract: A display apparatus is provided, which includes a display panel and a display controller. The display controller calculates an image average brightness of each image in a video signal from a host. When an absolute difference between a first image average brightness of a current image and a second image average brightness of a previous image is smaller than a predetermined value, the display controller activates a timer to obtain a timer value. When the timer value reaches a first duration, the display controller reduces brightness of each pixel in the current image by a first ratio. When the timer value reaches a second duration, the display controller reduces the brightness of each pixel in the current image by a second ratio. The second duration is longer than the first duration, and the second ratio is higher than the first ratio.
